Bailey Bridge Pier For Large Span Prefabricated Steel Bridge

Introduction of Bailey Bridge Pier

Bailey bridge pier serve as the support structures that hold up the bridge deck and transfer the weight of the bridge and any loads crossing it down to the ground or riverbed below. 

Bailey bridge pier is composed of foundation, pier body, top support and bridge span fixing device. The foundation consists of a base plate and anchor bolts; The pier is composed of 1m truss, Angle brace, HD321 Bailey panel standard truss, vertical cross brace 1, vertical Raker, vertical cross brace 2, horizontal wind structure. 

The pier of HD321 Bailey pier adopts 1m truss and HD321 Bailey panel standard truss as the foundation components to form square column pier. The top support of the pier is composed of beam staggered connection, and the space bar structure is connected between the pier. Adopting such a structural form is easy to meet the scale requirements of the structure, improve the adaptability of the pier structure, and give full play to the strength of materials. Increase structural stability.

Key features of Bailey bridge pier

Adjustable Height:

The number and length of the trestle legs can be varied to accommodate different gap depths.

This flexibility allows Bailey bridges to span a wide range of obstacles.

Lateral Stability:

The diagonal sway bracing members provide strong lateral support to the piers.

These features combined make the Bailey bridge pier design highly adaptable, versatile, and well-suited for temporary crossings in challenging environments. The portability and speed of assembly were critical factors in the widespread use of Bailey bridges during WWII and other conflicts.
